We\u0027re supposed to drop it at\nthe bridge.  However, because the check was placed in br_forward\ninstead of __br_forward, it\u0027s only effective if we are sending\nthe packet through a single port.\n\nThis patch fixes it by moving the check into __br_forward.\n\nSigned-off-by: Herbert Xu \u003cherbert@gondor.apana.org.au\u003e\nSigned-off-by: David S.
